Answer Key / Explanation : (c) -

(c)

Activation energy:  is the energy that must be possessed by the molecules in excess to the average energy at a given temperature to enter a chemical reaction

Relation between activation energy and enthalpy of a reversible reaction

If the reaction is endothermic in forward direction, then

If the reaction is exothermic in forward direction

For an endothermic reaction, where represents the enthalpy of the reaction in , the minimum value for the energy of activation will be slightly more than
